There is a certain sense of urgency that accompanies the arrival of new players, as well as a sense of hope for those who have already been to the World Cup, and who will have a greater appreciation for the team.
In many ways, this is the most significant World Cup for a generation, as they will get to witness the most important moments of their lives for the first time, and the memories of the past will surely be imprinted.
The only question is how well they get the hang of it, though, and will they be able to make a mark at this tournament?
The next generation of players are likely to be much more talented, as it will be hard for the younger players to make their mark in the world of international football.
But it will take time, as the new generation of talent is unlikely to be able pick up the ball immediately, and may struggle to cope with the speed of the game.
The new players might also be a little rusty, and not ready to handle the pressure of a World Cup.
In other words, it is the old players that will be the biggest challenge for the new players.
